Using CMPL(060) Results in the Program
When CMPL(060) is executed, the result is reflected in the Arithmetic Flags.
Control the desired output or right-hand instruction with a branch from the
same input condition that controls CMPL(060), as shown in the following dia-
gram. Here, the Equals Flag and output A will be turned ON when S
S +1, S .

Correct Use of CMPL(060)
Using CMPL(060) Results in the Program
Do not program another instruction between CMPL(060) and the instruction
controlled by the Arithmetic Flag because the other instruction might change
the status of the Arithmetic Flag. In this case, the results of instruction B might
change the results of CMPL(060).
